Hormones play a critical role in regulating appetite and weight management. Hormones such as ghrelin, known as the "hunger hormone", stimulate appetite, while leptin helps signal satiety. Imbalances in these hormones can lead to over-eating or difficulties in weight loss. Other hormones, like insulin, also impact fat storage and hunger sensations. Understanding these hormonal influences can guide individuals in making healthier choices that align with their weight management goals.
